The figure 6800 knife gate valve has an all cast stainless steel body and yoke with investment cast packing follower. It is a general purpose zero-leak bidirectional shutoff valve. Perimeter gate sealing is not pressure dependent, so there is no minimum differential needed for shutoff. Port sizing is similar to schedule 40 pipe, so the valve offers unrestricted flow and minimal pressure drop.
